2009 VW Jetta TDI Clean Diesel

After having TDI Golf 2004, new Jetta 2009 is a much smoother ride! It's comfortable, spacious and overall a nice car. I have a 6-speed Comforline Jetta and my biggest disappointment was milleage I get - my old car could run on one tank of diesel for 950 km and my new car covers only 750-800 km even though VW site states that it needs refilling at 1200km! That's a big difference and my driving style has not changed. I asked about it and supposedly there could be a number of reasons for it - none of which I would accept because, as I said, nothing in my driving style nor routes I take has changed.
Also, I'd like to comment on another owner's letter - yes, it makes noise even when shut down because its computer is shutting down everything (I was told as I too asked about it).

We bought a Jetta TDI Clean Diesel Comfortline Model - needed the leather seats due to owning dogs.
We test drove 3 TDI diesels as well as 9 other branded gas cars before deciding to go with the diesel - our daily commute is 91 kms return.  Each of the 3 we test drove were quiet, peppy and great little cars.  We went ahead and bought a new one, arrived to us with 31kms on the odometer.  The first weekend we had the car, we noticed many things about the way it drove.  It was overly noise when initially accelerating and when slowing to a stop, the shifting was very jerky - which has gotten much worse since.  The car also whistles constantly and when you shut it down, it continues to whistle for about 1 minute or more some times (coming from under the the drivers seat area).  There are also clicks and bangs that go along with the whistling.  The Sunroof seal failed right from the first day we had it, so we had the complete assembly replaced already.  We've also had the car in to the dealer 4 times to check the jerky shifting, last time they performed a complete factory reset (5800kms).  That lasted for the trip home and the next day it was back to very jerky downshifting.
The car is also uncontrollable upon accelerating from a stop.  Sometimes it accelerates nice and smooth, other times it jerks ahead like a rocket.  If the car is coasting forward the least bit, and the accelerator is pushed, the car takes a good 2 to 3 seconds to respond, which is getting to be very scary and dangerous in Toronto traffic.
We've about had enough of this piece of crap.  The salesman said we'd never go back to another car brand once we experienced a VW.  Oh contraire - we will never by VW again.

I just bought it and I love it only had 14 miles when I test drove it and bouth it on the spot my conmute is about 60 mi round trip and I'll get my money's worth.
